Hi Zehr,
There's a book by Dr. Mark Hyman that you might like
The UltraMind Solution: Fix Your Broken Brain by Healing Your Body First: M.D. Mark Hyman: 9780743570480: Amazon.com: Books
that has quizzes and specific recommendations for supplements as well as diet depending on the answers. I like Andrew Weil's stuff also. Both have lots of advice on the web as well.
I'LL SEE YOU IN HEALTH!! - vital
